摘要：
We report one patient with a de novo inversion duplication 18 (pter-->cen) and two cases of direct tandem duplication 18 (pter-->cen), one due to maternal inheritance and the other arising as mosaicism of unknown origin. The duplications are demonstrated by high resolution banding. They were verified by in situ hybridization with a paint specific for chromosome 18 and with DNA probe LI.84 specific for the centromere region of chromosome 18. FISH with the genomic DNA probe pHRR68 specific for 18p11.32 revealed a subtle deletion concomitantly involved in the case of inversion duplication 18p. The patients exhibit slight developmental delay/moderate mental retardation and only a few dysmorphic features. The literature on trisomy 18p is reviewed and the present cases are compared to it.
